本文实例为大家分享了Android实现分享功能的具体代码，供大家参考，具体内容如下

因为公司的需求，最近一直在做分享这一块的功能。大概有这样几种思路：

1.使用Intent调用andoird原生的分享功能；

2.使用第三方的sdk，比如ShareSdk或者友盟；

3.去对应的平台下载jar包，参考官方设计文档写出自己的分享demo，但这种一般也比较复杂，尤其搞不懂qq和微信一家公司的，为什么微信那么麻烦。

不废话了，直接上代码：

一. 新建ShareUtil.java类

import java.io.File; import android.content.ComponentName; import android.content.Context; import android.content.Intent; import android.content.pm.PackageManager; import android.content.pm.PackageManager.NameNotFoundException; import android.net.Uri; import android.text.TextUtils; import android.widget.Toast; public class ShareUtil { private Context context; public ShareUtil(Context context) { this.context = context; } public static final String WEIXIN_PACKAGE_NAME = ""; public static final String QQ_PACKAGE_NAME = ""; // public static final String ; /** * 分享文字 * @param packageName * @param content * @param title * @param subject */ public void shareText(String packageName,String className,String content,String title,String subject){ Intent intent =new Intent(); intent.setAction(Intent.ACTION_SEND); intent.setType("text/plain"); // if(null != className && null != packageName && !TextUtils.isEmpty(className) && !TextUtils.isEmpty(packageName)){ // // }else { // if(null != packageName && !TextUtils.isEmpty(packageName)){ // intent.setPackage(packageName); // } // } if(stringCheck(className) && stringCheck(packageName)){ ComponentName componentName = new ComponentName(packageName, className); intent.setComponent(componentName); }else if(stringCheck(packageName)){ intent.setPackage(packageName); } intent.putExtra(Intent.EXTRA_TEXT, content); if(null != title && !TextUtils.isEmpty(title)){ intent.putExtra(Intent.EXTRA_TITLE, title); } if(null != subject && !TextUtils.isEmpty(subject)){ intent.putExtra(Intent.EXTRA_SUBJECT, subject);

// } // } if(stringCheck(className) && stringCheck(packageName)){ ComponentName componentName = new ComponentName(packageName, className); intent.setComponent(componentName); }else if(stringCheck(packageName)){ intent.setPackage(packageName); } intent.putExtra(Intent.EXTRA_TEXT, content); if(null != title && !TextUtils.isEmpty(title)){ intent.putExtra(Intent.EXTRA_TITLE, title); } if(null != subject && !TextUtils.isEmpty(subject)){ intent.putExtra(Intent.EXTRA_SUBJECT, subject); } intent.putExtra(Intent.EXTRA_TITLE, title); Intent chooserIntent = Intent.createChooser(intent, "分享到："); context.startActivity(chooserIntent); } /** * 分享图片 */ public void shareImg(String packageName,String className,File file){ if(file.exists()){ Uri uri = Uri.fromFile(file);

}else if (stringCheck(packageName)) { intent.setPackage(packageName); } intent.putExtra(Intent.EXTRA_STREAM, uri); Intent chooserIntent = Intent.createChooser(intent, "分享到:"); context.startActivity(chooserIntent); }else { Toast.makeText(context, "文件不存在", 1000).show(); } } /** * 分享音乐 */ public void shareAudio(String packageName,String className,File file){ if(file.exists()){ Uri uri = Uri.fromFile(file); Intent intent = new Intent(); intent.setAction(Intent.ACTION_SEND); intent.setType("audio/*"); if(stringCheck(packageName) && stringCheck(className)){ intent.setComponent(new ComponentName(packageName, className)); }else if (stringCheck(packageName)) { intent.setPackage(packageName); } intent.putExtra(Intent.EXTRA_STREAM, uri); Intent chooserIntent = Intent.createChooser(intent, "分享到:"); context.startActivity(chooserIntent); }else { Toast.makeText(context, "文件不存在", 1000).show(); } } /** * 分享视频 */ public void shareVideo(String packageName,String className,File file){ setIntent("video/*", packageName, className, file); } public void setIntent(String type,String packageName,String className,File file){ if(file.exists()){ Uri uri = Uri.fromFile(file); Intent intent = new Intent(); intent.setAction(Intent.ACTION_SEND); intent.setType(type); if(stringCheck(packageName) && stringCheck(className)){ intent.setComponent(new ComponentName(packageName, className)); }else if (stringCheck(packageName)) { intent.setPackage(packageName); } intent.putExtra(Intent.EXTRA_STREAM, uri); Intent chooserIntent = Intent.createChooser(intent, "分享到:"); context.startActivity(chooserIntent); }else { Toast.makeText(context, "文件不存在", 1000).show(); } } /** * 分享多张图片和文字至朋友圈 * @param title * @param packageName * @param className * @param file 图片文件 */ public void shareImgToWXCircle(String title,String packageName,String className, File file){ if(file.exists()){ Uri uri = Uri.fromFile(file); Intent intent = new Intent(); ComponentName comp = new ComponentName(packageName, className); intent.setComponent(comp); intent.setAction(Intent.ACTION_SEND); intent.setType("image/*"); intent.putExtra(Intent.EXTRA_STREAM, uri); intent.putExtra("Kdescription", title); context.startActivity(intent); }else{ Toast.makeText(context, "文件不存在", Toast.LENGTH_LONG).show(); } } /** * 是否安装分享app * @param packageName */ public boolean checkInstall(String packageName){ try { context.getPackageManager().getPackageInfo(packageName, PackageManager.GET_ACTIVITIES); return true; } catch (NameNotFoundException e) { e.printStackTrace(); Toast.makeText(context, "请先安装应用app", 1500).show(); return false; } } /** * 跳转官方安装网址 */ public void toInstallWebView(String url){ Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setData(Uri.parse(url)); context.startActivity(intent); } public static boolean stringCheck(String str){ if(null != str && !TextUtils.isEmpty(str)){ return true; }else { return false; } } }

其中微信的分享只能分享文字和图片，不能单独分享图片或者文字。
